Running and Defense still wins championships right?

Whenever NFL analysts bring up playoff football, the two most important rules are having a good defense and being able to run the ball. However, the last four Super Bowls have featured all passing teams with the exception of the Steelers. So I say that to say this, what's the formula to winning in the playoffs? Is it still pounding the ball and defense or is that now obsolete?

its honestly been years since i heard people say that running games and defense wins titles.

that's not to say you don't need those two things. you don't have to be great at anything but you have to be able to be able to have a good enough run game and good enough pass game to be able to do those things when the situation warrants. You don't need a great defense, but you need to be able to make stops in crucial moments of the game.
